Accident Description
The pilot reported that the approach and landing were normal, but during the landing rollout, the brakes were found to be inoperative. The aircraft subsequently departed the left side of the runway and collided with a fence surrounding a ballpark.
Post-Crash Examination
Examination of the hydraulic system after the accident revealed that the hydraulic reservoir was empty. Additionally, the main accumulator and the thrust reverser accumulator had no air charge.
Occupant Status
All four occupants escaped the aircraft uninjured.
Probable Cause
The official findings identified three contributing factors:
- Hydraulic system reservoir - low level
- Aircraft preflight - poor (pilot in command)
- Maintenance, service of aircraft/equipment - improper (other maintenance personnel)
These issues led to a hydraulic system failure, resulting in brake loss during landing rollout and subsequent overrun, culminating in collision with a fence.
